First Kristen Stewartdebuted a backless, black Zuhair Murad jumpsuit last week for the premiere of Twilight: Breaking Dawn – Part 2, and last night Jessica Biel followed her lead in a silver Oscar de la Renta pantsuit at the Hitchcock premiere.

Like K-Stew's, Jessica's outfit was sheer, showing off her legs and torso, but was boxier and less sexy, with full sleeves and oversized top. Do you think she pulls it off?

Scarlett Johannson, meanwhile, opted for a strapless, leaf-patterned Rodarte dress with Gucci heels — definitely a younger and more feminine look than Jessica's, don't you think?
